But back to your point, the toll roads I travel on charge more for semi-trucks than they charge for passenger vehicles.
I understand the thought that the public is investing in these wires, so they own them, but the public invests in all sorts of industries, including pharmaceuticals (via the NIH), vehicles (buying GM), mortgages (fannie may, aig), but yet they don't regulate what gm charges for cars or Pfizer charges for their drugs.
I wonder why we believe it is okay for the govt to meddle in some areas and not others? Where and how do we draw the line?
